pinctrl: remove sirf atlas/prima drivers

CSR SiRFatlas7 GPIO controller bindings

Required properties:

- compatible	: "sirf,atlas7-gpio"

- reg		: Address range of the pinctrl registers

- interrupts	: Interrupts used by every GPIO group

- gpio-banks	: How many gpio banks on this controller

- gpio-controller : Indicates this device is a GPIO controller

- interrupt-controller  : Marks the device node as an interrupt controller

The GPIO controller also acts as an interrupt controller. It uses the default

two cells specifier as described in Documentation/devicetree/bindings/

interrupt-controller/interrupts.txt.

Example:

	gpio_0: gpio_mediam@17040000 {

		compatible = "sirf,atlas7-gpio";

		reg = <0x17040000 0x1000>;

		interrupts = <0 13 0>, <0 14 0>;

		#gpio-cells = <2>;

		#interrupt-cells = <2>;

		gpio-controller;

		interrupt-controller;

		gpio-banks = <2>;

		gpio-ranges = <&pinctrl 0 0 0>,

				<&pinctrl 32 0 0>;

		gpio-ranges-group-names = "lvds_gpio_grp",

					"uart_nand_gpio_grp";

	};

	leds {

		compatible = "gpio-leds";

		led1 {

			gpios = <&gpio_1 15 0>;

			...

		};

		led2 {

			gpios = <&gpio_2 34 0>;

			...

		};

	};

Please refer to gpio.txt in this directory for details of the common

gpio properties used by devices.

CSR SiRFatlas7 pinmux controller

Required properties:

- compatible	: "sirf,atlas7-ioc"

- reg		: Address range of the pinctrl registers

For example, pinctrl might have properties like the following:

	pinctrl: ioc@18880000 {

			compatible = "sirf,atlas7-ioc";

			reg = <0x18880000 0x1000>;

			a_ac97_pmx: ac97@0 {

				ac97 {

					groups = "audio_ac97_grp";

					function = "audio_ac97";

				};

			};

			...

			sd2_pmx: sd2@0 {

				sd2 {

					groups = "sd2_grp0";

					function = "sd2";

				};

			};

			...

			sample0_cfg: sample0@0 {

				sample0 {

					pins = "ldd_0", "ldd_1";

					bias-pull-up;

				};

			};

			sample1_cfg: sample1@0 {

				sample1 {

					pins = "ldd_2", "ldd_3";

					input-schmitt-enable;

				};

			};

			sample2_cfg: sample2@0 {

				sample2 {

					groups = "uart4_nopause_grp";

					bias-pull-down;

				};

			};

			sample3_cfg: sample3@0 {

				sample3 {

					pins = "ldd_4", "ldd_5";

					drive-strength = <2>;

				};

			};

	};

Please refer to pinctrl-bindings.txt in this directory for details of the common

pinctrl bindings used by client devices.

SiRFatlas7's pinmux nodes act as a container for an arbitrary number of subnodes.

Each of these subnodes represents some desired configuration for a group of pins.

Required subnode-properties:

- groups : An array of strings. Each string contains the name of a group.

- function: A string containing the name of the function to mux to the

  group.

  Valid values for group and function names can be found from looking at the

  group and function arrays in driver files:

  drivers/pinctrl/pinctrl-sirf.c

For example, pinctrl might have subnodes like the following:

	sd0_pmx: sd0@0 {

		sd0 {

			groups = "sd0_grp";

			function = "sd0";

		};

	};

	sd1_pmx0: sd1@0 {

		sd1 {

			groups = "sd1_grp0";

			function = "sd1_m0";

		};

	};

	sd1_pmx1: sd1@1 {

		sd1 {

			groups = "sd1_grp1";

			function = "sd1_m1";

		};

	};

For a specific board, if it wants to use sd1,

it can add the following to its board-specific .dts file.

sd1: sd@12340000 {

	pinctrl-names = "default";

	pinctrl-0 = <&sd1_pmx0>;

}

or

sd1: sd@12340000 {

	pinctrl-names = "default";

	pinctrl-0 = <&sd1_pmx1>;

}
